Managerial Economics: A Guide to Managerial Economics by Rupesh Ranjan is a comprehensive introduction to the economic principles and analytical tools that support effective managerial decision-making. The book connects economic theory with practical business situations, helping readers understand how managers make choices regarding resources, production, pricing, investment, markets, and business strategy.

The book is organised into four broad blocks. It begins with the basics of managerial economics, introducing fundamental economic concepts, the role of managerial economics in decision-making, consumer behaviour, and demand analysis. It then moves to supply and production, examining supply analysis and production functions.

The third block focuses on cost and break-even analysis, including new-product pricing decisions such as penetration and price-skimming strategies, along with profit and investment analysis. The final block examines macroeconomic factors, national income, and economic regulations of business, placing managerial decisions within the wider economic environment.

A central theme of the book is that managerial economics is not simply about understanding economic theories; it is about using economic reasoning to make informed decisions under conditions of limited resources, changing markets, uncertainty, competition, and regulatory constraints.

Designed for students, management learners, business professionals, researchers, and readers interested in economics, the book aims to provide a structured bridge between economic concepts and managerial practice. It encourages readers to look at business decisions through the interconnected lenses of demand, supply, costs, production, pricing, profitability, investment, and the broader economy.

Managerial Economics: A Guide to Managerial Economics therefore serves as both an academic introduction and a practical framework for understanding how economic thinking can contribute to better organisational decision-making.
